Having received this just today in the post, I can personally say that this is the finest Piggyback guide produced to date. My initial reaction was that this guide- or rather book, was very thick; over 340 pages to be precise. Increasing the weight and support of the book was the hardback cover, which no doubt will prevent curly ends which even the best kept softback books are subject to suffer from.
Having had a deeper look into the guide, Piggyback's use of maps, detail and presentation instantly convey towards the reader that it is an extremely detailed resource which has been very professionally designed. If you had any of the previous guides from Piggyback, particularly the Final Fantasy X guide, you will notice a far larger enemies section, as well as more statistical tables.
For those interested, this Limited Edition guide is as pictured on the Amazon photo, but comes with an additional white traditional cover slip over the book, as well as a placeholder.
If you prefer to have guides to complete games, get this guide. If you don't normally use a guide to complete games, get this guide. It will prove remarkably useful for the plethora of extras in this game, as well as for obtaining the best equipment and more. A must buy.
